Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic device connection accessories technology, and more specifically, to a fixing and anti-detachment device and connector. Background Technology
[0002] HDMI (High Definition Multimedia Interface) connectors transmit uncompressed high-definition video and audio signals between devices (such as TVs, monitors, projectors, computers, Blu-ray players, set-top boxes, and audio equipment) via cables. The connection between the HDMI plug and socket is typically a plug-and-play connection, relying solely on the contact friction between the metal contacts of the plug and socket for positioning. Under gravity, this can easily lead to loosening and poor contact over time. Existing technology includes HDMI plug cables with integrated fixing devices, which can secure the HDMI plug cable. However, this design is custom-made, lacks versatility, and requires separate purchase. Furthermore, existing fixing devices are inconvenient to disassemble, have poor reusability, poor compatibility, and are difficult to adapt to different manufacturers' HDMI plugs with varying sizes.
